Coccygeal osteosarcoma – a report in three cows
The report describes a rare occurrence of coccygeal osteosarcoma in three middle aged adult cows. All cows had a hard ulcerated swelling at the base of tail from 4-6 months making it heavy and stiff. Lateral radiographs demonstrated lysis of the initial coccygeal vertebrae with sunburst appearance. The tails were amputated, as cranial as possible, under general anaesthesia. Histology confirmed coccygeal osteosarcoma in all the cows. The cows lived a quality life for 3-6 months, post-operatively, till reoccurrence and died within 4-12months. In conclusion, coccygeal osteosarcoma bears a poor prognosis due to delay in presentation, extensive involvement and consequent re-occurrence.
